The development and initial testing of a complete 7T, 32-channel RF transmit system is described. This RF subsystem, consisting of a new RF sequencer/controller, independent waveform generation, and power amplifiers, is designed to be an add-on expansion to an existing 7T imager. The new RF capability will enable research into the tradeoffs in the various questions/tradeoffs relating to the number of available channels. The system is modular in 8-channel increments, and the architecture allows relatively straightforward integration into most scanners
